PSB Alpha P3 Bookshelf Stereo Speakers Pair Black For Sale

Compactand Versatile Without Sacrificing Performance

The Alpha P3is a small two-way bookshelf speaker that connects to any stereo or hometheater system to fill the room with powerful, crystal-clear sound. Featuring acustom 4.5\" woofer and aluminum dome tweeter that uses a waveguide toperfectly match the low and high frequencies for a smooth transition, the P3delivers improved directivity and flattens the frequency response for a morenatural sound. It also leverages specially textured woofer cones and a uniqueport tube design that uses bass flex to add back energy and extend the bassfrequencies even lower and without any distortion.

HearBeautiful Texture and Detail

All newAlpha Series models employ a .75\" black anodized aluminum dome tweeterthat extends the high-frequency response beyond the Alpha\'s originalmeasurements and minimizes distortion for a rich, balanced listeningexperience. A waveguide on the front of the tweeter works to perfect on andoff-axis performance while smoothing the response for improved resolution anddetail. The ferrofluid cooled tweeter on the P3 has also been precisionengineered to sit below the woofer to provide precise stereo imaging at anyheight.

PowerfulWoofer with Dual Layer Voice Coils

At the heartof every good speaker is a great woofer that produces low distortion and highoutput levels. With the new Alpha Series, the 4.5\" woofer employs duallayer voice coils with a very powerful magnet structure and a cone that is madefrom a special textured polypropylene compound that prevents breakup. With bassreflex loaded through Paul’s original port tube design from the ’70s, thewoofer adds back wave energy to extend the bass response and improve efficiencydown to 43Hz.

Custom-Builtand Perfected

The AlphaSeries’ new crossover wasn’t custom designed to simply just direct low and highfrequencies to the woofer and tweeter. It was re-engineered to control thedirectivity and flatten the frequency response while utilizing an unusuallycomplex acoustic Butterworth low-pass filter that is designed to get a perfectblend between the drivers and keep distortion at its lowest even at highvolumes.

UniqueModular Cabinet Design

The P3 has aunique combination of wall thickness and bracing to control resonances andprovide a perfect platform for the driver components. The P3 cabinet’s internaldamping material was first used in PSB’s most high-end models, and has now beenadopted by the Alphas and positioned precisely for optimum effectiveness. Apremium woodgrain vinyl finish and chrome front baffle highlights combine withmagnetically attached grilles to provide a rich and timeless design.
